Sunlight has repeatedly shown to be counterproductive. Some people use any kind of platform they can get, any sort of media attention, to spread their views. They don't care that they get ridiculed, because their followers just see that as further proof of media conspiracies and bias. It just confirms and reinforces their prejudices.

Deplatforming works. Free speech does not mean you have a right to use any platform you choose, nor does it shield you from the consequences of your speech.

The deeper and darker the corners where they hide and the harder it is to stumble across by accident, the harder it is for them to spread their viewpoints.

See Voat and Gab for relevant examples. Only the really hardcore believers went there when Reddit and Twitter said "that's it, get off our platforms".
